CAUTION:
• When the tool stops automatically after
the switch is released during impact-
mode tightening and then reengaged
within 1 second, the red lamp will light up
to indicate the risk of excessive torque
application as a result of retightening.
NOTE
• The tightening confirmation lamp will not
turn on under the following conditions:
• When the torque clutch is set to “F”
• During reverse rotation operation
• The lamp turns off when the tool is in
operation.

(1) LED light
Pressing the button toggles the LED light on
and off.
The light illuminates with
very low current, and
it does not adversely affect the performance of
the
tool during use or its battery capacity.
CAUTION:
• The built-in LED light is designed to illu-
minate the small work area temporarily.
• Do not use it as a substitute for a regu-
lar
flashlight, since it does not have
enough brightness
.
Caution
: DO NOT STARE INTO BEAM.
Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous radiation exposure.
(2) The battery indication lamp
• Use the battery indication lamp to check
how much power is left in the battery.
• Battery life varies slightly with ambient tem-
perature and battery characteristics. The
lamp is designed to provide a rough indica-
tion of remaining battery life.

Automatic power-off function
• The automatic power-off function is designed
to prevent a loss of tightening torque due
to reduced battery voltage. Once it has
been activated, the tool will not operate until
the battery pack has been charged (or re-
placed with a fresh unit), even if the trigger is
depressed.
